Embodiment 1

[0032] Such as Figure 1 to Figure 2 As shown in the figure, an intelligent and rapid judgment system for the surrounding rock level of a tunnel includes a tunnel face, and a construction platform is arranged in front of the tunnel face, and also includes a three-dimensional laser scanner, an infrared detector, a host computer, a laser pointing device, an LED display and The intelligent electronic rebound hammer, wherein the three-dimensional laser scanner, infrared detector, host, laser pointing device and small LED display are respectively arranged on the construction platform of the tunnel face, the intelligent electronic rebound hammer is an independent device, and the The intelligent electronic rebound hammer is connected to the host through a wireless network. The host includes a wireless data interface for matching the intelligent electronic hammer.

Embodiment 2

[0034] Such as Figure 1 to Figure 4 As shown, an intelligent and rapid determination method for the surrounding rock level of a tunnel includes the following steps:

[0035] A. After blasting the face every time to find the top and clear the danger, the three-dimensional laser scanning of the face is carried out to obtain the three-dimensional space data of the joint fissure structure of the face, and the host face is used to calculate the occurrence of joint fissures and construct the three-dimensional structure of the surrounding rock of the face Rock mass structure model;

[0036] B. Through the infrared detection and scanning of the working face, the groundwater development of the working face is obtained, and after calculation by the host computer, it is superimposed with the data of the rock mass structure model. The groundwater development of the working face includes the data of seepage water points and surfaces;

[0037] C. The host computer calculates the strength ...

Abstract

The invention discloses an intelligent and fast judgment system for the surrounding rock level of a tunnel, which comprises a tunnel face, a construction platform is arranged in front of the tunnel face, and also includes a three-dimensional laser scanner, an infrared detector, a host computer, a laser indicating device, and an LED display and an intelligent electronic rebound rebound instrument, the present invention solves the problems existing in the prior art that cannot guarantee the accuracy and objective fairness of the determination of the surrounding rock level, and provides an intelligent and fast determination system and method for the surrounding rock level of the tunnel, which can guarantee The accuracy and objective fairness of surrounding rock grade determination. It can be used for the construction face of all rocky tunnel sections, and the real-time judgment of the face condition can effectively improve the construction efficiency and save manpower and material resources; through quantitative data collection and intelligent system judgment, it can ensure the consistency of judgment scale and Accuracy, to avoid misjudgment due to inexperienced engineers.

Description

technical field [0001] The invention relates to the technical field of tunnels, in particular to an intelligent and fast judgment system and method for surrounding rock levels of tunnels. Background technique [0002] The compass used in the stratum occurrence measurement is the existing equipment, and the three-dimensional laser scanner is also the existing equipment. [0003] At present, the determination of the surrounding rock level of the face of the tunnel construction depends on the investigation, measurement and inspection of the face by the geological engineer on site, the geological information is recorded by filling in the form, and the surrounding rock level is determined after the corrected BQ value is obtained through simple calculations . There are two problems in the above scheme, one is time-consuming and labor-intensive, and it is difficult to meet the requirements of on-site construction procedures and progress; the other is that due to the limitation of ...
